T0 (0% whom, it may concern:

Be it known that I, WILLIAM HENRY Pon- TER, a citizen of the UnitedStates, residing in the city, county, and State of New York, haveinvented certain new and useful Improvements in Catalytic Gas Lighters,of which the following is a specification.

My invention relates to catalytic gas-lighters; and it consists of acatalytic gas-lighting tip embodying the various features ofconstruction, substantially as hereinafter more particularly set forth.

H Referring to the accompanying drawings, Figure 1 is a front elevationof a complete lighting-tip. Fig. 2 is a side elevation of the same. Fig.3 is a vertical section of Fig. 2. Fig. 4 is a rear elevation of thetip. Fig. 5 is a vertical section of Fig. 1 with the material and wiresremoved. Fig.6 is a perspective view of a hood, showing the wiresaffixed thereto; and Fig. 7 is a View illustrating one way of applyingthe catalytic material to a burner of the incandescent type.

In the drawings, A represents the body of the tip, to which the hood Bisattached, which hood maintains the catalytic material C in position andforms a support for the wires D. The wires may be attached in anydesired manner, and, as shown, the fine wires, preferably of platinum,are made into a bundle or cable and secured in an opening I) in thehood, and the free ends of the wires prefer ably are bent upward, so asto occupy a position at or near the side of the flame and not withinreach of the hottest portion thereof.

It very fine platinum wires were placed on the tip without a hood in therelation shown, the ends would become enlarged into globules by fusionand the wires would be less efficient. The hood acts as a protector,preventing free access of air to that part of the flame near which theends of the wires are located. The number of metallic wires used is notof importance; but I generally use from six to twenty, so as to make thelighting expeditious.

When a hood is placed on an ordinary gastip, it is apt to bring theflame toward one side. In order to avoid this inconvenience, the tip isso formed as to produce a flame normally leaning toward one side, andwhen the hood is present the flame will take aperpendicular position. Aninclination of the flame toward one side of about four degrees when thetip is without a hood will generally be found to be suflicient toproduce a per pendicular flame when a hood is used.

The inclination of the flame without the hood may be produced in anydesired manner, and in the form of tip taken to illustrate my inventionthe sides a of its dome-like end are compressed to form a passage 0between the indented portions and substantially cylindrical channels 0 cat each side, and by making the channel 0 slightly larger than thechannel 0 the normal position of the flame will be slightly inclined toone side, which inclination is overcome by placing the hood in theposition shown.

In Fig. 7 I indicate one way of applying the catalytic material to aburner of the incandescent type, in which the material C and Wires D aresecured in any desired manner to the dome of the burner within thegas-outlet, and as the gas usually flows through an annular opening aliood such as above described is not necessary.

WVhat I claim is 1. Acatalyticlighting-tipcomprisiugabody having apassage for the gas, a hood located at one side of the passage,catalytic material supported by the hood and fine metallic wires mountedin the hood and projecting toward the side of the flame.

2. Acatalyticlighting tip comprisingabody having a passage for the gas,a hood located at one side of the passage, catalytic material supportedby the hood and fine metallic wires projecting toward the side of theflame and bent upward so as not to extend into the hot portion of theflame.

3. A catalytic lighting-tip consisting of a body, a hood, fine metallicwires, and catalytic material so located as to be protected by the hoodagainst fusion by the flame, substantially as described.

4. A catalytic lighting-tip consisting of a tip producing a flameleaning toward one side, a hood located on said tip so as tosubstantially overcome the inclination of the flame,

and catalytic lighting material located in tllel In testimony whereof Ihave signed my hood, substantially as described. I name to thisspecification in the presence of IO 5. A catalytic lighting-tipconsisting of a two subscribing Witnesses.
